Question

因此，我对Tkinter和整个Python还是很陌生。我正在一个项目，该项目从互联网上获取歌词，或者只是向您显示歌词，或者使用马尔可夫链来生成随机歌曲。我已经使代码工作了，我现在正尝试实现GUI。我已经到了可以输入歌曲和歌手的地步，程序会为您提供歌词。目前，歌词仍会在控制台中出现。我现在正在尝试将歌词导入GUI，但是当我尝试将其放在文本中时，该歌词已被删除。我在事物的tkinter部分使用了一个教程，所以我不确定代码的哪一部分是相关的。有问题的文本在GetLyrics类中。（lyric_label）当前仅使用“ example”作为占位符。提前非常感谢您，如果我在这篇文章中做错了什么，请告诉我。

这是问题的图片：

Answer 1

将rely的值减小为.8或.75或以下类似内容：

lyric_label.place(relx = .1, rely = .85)

更改为：

lyric_label.place(relx = .1, rely = .8)

或

lyric_label.place(relx = .1, rely = .75)
